GAS RANGE.

Application led June 19,

rllhis invention relates to gas bin-ners, and has tor its object to provide a new and iinproved device oi. thie (lescription by naoans oi which a greater e'iiieieney is secured :in the con '5` suinptiiin o' The :invention has as another object to f-tecnre a greater eliicicncy in the utilir/iation et die heat generally. The inver "irV has other objects which are more partie `larly pointed out in the tollowino' deiw scription. Reif now to the drawings Iig. i, is a pian .row et the burners with parte broken away;

Fig. 2 is a sectional View taken on line 2--2 8 is a side View o if Fi i Il. p is a bottoni 'View ot Fig. i.;

Lilie nuinerafts refer to like parts throughout the several iigures.

In the dran/'ii I have shown the particiilar construction et the burners. In this coin struction each burner is provided with a central tube El. 'lhe tube S) oit' the burners is surrmindod by an outer tubo et Wliich is connected with source ont gas sir Iy, sach as 'he bnrner supply pipe The tube i) crtends through the conn e 1" )n ot the tube 4l nath th e source oi gras supply, and is open both at its lower nd its upper ends as cleariy shown in Ii D7 1o that a may pass thereth roua'h. The tubes |par througgifi the part l0, ithere are openings lOin this part around each tube li o the t when the burner is bi'irning, air passes up through the openings i0 to the thune. itt will thus be seen that the gas passes into the space between the tubos Si and 45" to its discharge point and that upon eaeh side oit lthe gras discharge openinlgjg, air is also discharged, the air on one side comingthrough the tube 9, and the air on the other siue 'coming tlirouggh the opening; il). This construction greatly decreases the anionnt ont lgas required and increases the eiliciene'ji7 of the rapire.

at iii-oni the burners passes throiugh the jewa'ys 2 and 3&1 at the top oi the oven and then passes airing' down the ends o'lf the ovens 'throuoh the passageways 2" and 3" and then alone1 the bottoni oi the oren through the passagewajrs 2 and 3:3 and their passes into the 1922. Serial No. 569,285.

passageways 2I and 3d at the back ot the oven, as shown in Figs. 2, 3 and 4, and then to the chimney ll. rlhe passageways 2c and 3 are preferably provided with baille plates 2" and P0 to properly distribute the heat. Beneath the ovens are passa geways l2 and 12L Which admit air to the 'chamber 13 containing the burners. rlhe passageways 12 and 12 preterably have thin conducting` Walls so that the heat from the gases .in the passageways 2 and 3 heat this incoming air, thus causing the air which is supplied to the burners e to be heated be'ore being supplied to the burners, and 'this heated air also tends to heat the gas passing?,` to the burners tlirougjh the tubes 7 and 8. his construction increases the eticiency of the burner.

I elaiin:

l. A burner having a pipe open at both ends through which air passes, a second pipe surroundingl the iii-st pipe and spaced there-frein, the spare between the two pipes `closed at one end and open at the other end, a perforated plate through Wh ich the open ends ot both of said pipes project, the opening in the plate bein larger than the outer pipe so as to leave an air space surroundingl it through which air passes when the burner is operated, and ineans :tor admitting gas in the space between the two pipes, the ends of said pipes being substantially flush with the top ot said perforated plate.

2. A burner conlprisingl a horizontal pipe having' separated openings extending' lateral- 1y theretlnough, projecting; pipes Connected with the horizontal pipe and surroundingl the openings, open air pipes extending through said openings in said horizontal pipe, a perforated plate into which the ends ot said projecting' pipes and open air pipes are received, the perlforations in the plate beingl larger than the projecting pipes so as to provide a space sin'roundingg thorn through Which air may pass, and means for admitting' gas to said horizontal pipe.

Signer'l at Chicago, eonnty of Cook, and State ot Illinois, this 2nd day oi June, 1922.
